Factors associated with anemia among pregnant women attended antenatal care: a health facility-based cross-sectional study

Abstract

Anemia is characterized by a decline in the number or size of red blood cells and Hb concentration, which results in impairment capacity to transport oxygen. It is a major cause of indirect maternal mortality. Anemia is largely preventable and easily treatable, if detected in time; however, it remains one of the leading causes of maternal morbidity and mortality, especially in developing countries. This study aimed to assess factors associated with anemia among pregnant women who attended antenatal care.

Methods: A health facility-based cross-sectional study was conducted from 1 February 2020 to 2 March 2020 among 420 pregnant women. The data were collected by systematic random sampling technique, entered into a computer using EpiData 3.5, and analyzed using the Statistical Package of Social Sciences 23.0 version. Bivariate and multivariable logistic regression analyses were done to estimate the crude and adjusted odds ratio with a CI of 95% and a P-value of less than 0.05 considered statistically significant. Frequency tables, figures, and descriptive summaries were used to describe the study variables.

Results: The overall prevalence of anemia was 32.9% (95% CI: 28.6-37.4), and it was higher in rural than urban pregnant women (45 vs. 23%), respectively. In multivariable analysis women who are found in the age group of greater than or equal to 30 years (AOR=3.45, 95% CI=1.22-9.78), rural residency (AOR=3.51, 95% CI=1.92-6.42), low family income (AOR=3.10, 95% CI=1.19-8.08), multiparty (AOR=2.91, 95% CI=1.33-6.38), a short interpregnancy gap (AOR 3.32, 95% CI=1.69-6.53), not taking iron and folate (AOR=4.83, 95% CI=2.62-9.90), third trimester of pregnancy (AOR=3.21, 95% CI=1.25-8.25), poor minimum dietary diversity score (AOR=3.54, 95% CI=1.58-7.95), undernourished (AOR=4.9, 95% CI=2.19-7.64), poor knowledge of anemia (AOR=3.19, 95% CI=1.72-5.93), consumption of coffee always after meal per day (AOR=3.24, 95% CI=1.42-7.42), having a history of irregular menstruation, and antepartum hemorrhage were significantly associated with anemia in pregnant women.

Conclusion: This study showed that the prevalence of anemia in pregnant women in this study area was a moderate public health problem. The author suggest emphasizing the education and counseling of women on the advantage of taking the supplemented iron and folic acid. Health care providers should have to advise women to stay for at least 2 years before the next pregnancy to reduce the risk of adverse maternal and infant outcomes. Awareness creation in the community on the utilization of insecticide-treated bed nets is also needed.
